Good luck on your first flight. I had my first flight a couple weeks ago and was very excited that I no longer needed the seat belt extender. However, once I landed I was unable to eat and had difficulty even drinking liquids. It took a few hours to be able to get liquids and soft food down without restriction. The next day I was able to eat solids, but had to do so much slower than ever before. On my return flight, I didn't experience the same complications, but since my flight I have had intermittent difficulties. One meal I will have no trouble, the next I will vomit after my first couple bites of solid food. I'm trying to decide if I should have fluid removed. It's been two weeks since my flights so I would think by now things should have settled down.
Keep me posted. I'm curious to see if anyone else experiences problems after flying.
